Swing clamps with position monitoring,
bottom flange type, reinforced swing mechanism, without overload protection device,
double acting, max. operating pressure 500 bar

Inductive proximity switches are used for position monitoring. They are installed in the housing of the swing clamp. The control cap for activation of the proximity switches is connected to the clamping arm to enable permanent position monitoring of the clamping arm.

N-S035  |  Data sheet B1.8821 German  English  French  Italian  Spanish






Position-flexible fixture clamp
max. clamping force 8 kN, jaw width 40 mm
double acting, max. operating pressure 250 bar

Position-flexible fixture clamps can additionally clamp and support a workpiece, which is already positioned and clamped in fixed stops, at unstable workpiece sections.
Due to their compact design they can be arranged in a very limited space. Fixture clamps are especially suitable for series manufacturing in automated mode.

N-S034  |  Data sheet I4.130 German  English  French  Italian  Spanish






Swing clamp with sturdy swing mechanism
cartridge type, with optional position monitoring,
without overload protection device, double acting, max. operating pressure 350 bar

All swing clamps of this data sheet issue 9-08 (September 2008) were redesigned - with the objective to increase the clamping force or to use also longer clamping arms. The result is quite respectable:
=> up to 75% higher clamping force!
=> now 75% longer clamping arms can be used with the same clamping force!
  
N-S033  |  Data sheet B1.852 German  English  French  Italian  Spanish






Bore clamp - eccentric version
for bore diameter 9.3 to 9.8 mm, 3 different clamping inserts,
double acting, max. operating pressure 250 bar

Due to the small dimensions at the effective point and the compact design clamping of workpieces with raised parts right next to the bore to be clamped is possible.
The bore clamp can be equipped with 3 different clamping inserts: with centring, with compensation and without centring.

N-S032 |  ROEMHELD information S008  German  English  Italian






Compact swing clamp with pneumatic clamping monitoring
cartridge type, double acting, max. operating pressure 250 bar

The compact clamp particularly excels by its minimum dimensions. Due to the integrated pneumatic clamping monitoring it is possible to check the availability of the workpiece and the clamping pressure.
Two different cartridge types, each in four sizes, offer a high flexibility for the design of clamping fixtures.

N-S031 |  ROEMHELD information S010  German  English  Italian






Swing clamp with self-locking function
double acting

The new swing clamps maintain the total clamping force by a patented self-locking device if hydraulic pressure is cut off or drops. Locking of the piston rod is made by a seperately-acting self-locking locking piston. Locking at the piston rod is positively. Actually there are two sizes with optional inductive or pneumatic position monitoring.

Hydraulic high-pressure hoses
assembled ready for connection, max. operating pressure 250/500 bar

Completely pressed high-pressure hoses with nominal diameter 4 and 6 with mounted union nut.
The new data sheet F 9.361 replaces data sheet F 9.360, since the versions with pipe sockets with removable cutting ring and union nut are no longer allowed for safety reasons.

Assembly and handling technology


Clamping modules - mechanical
Clamps or swing clamps with universal clamping plate,
max. clamping force 6 and 10 kN

These modulog clamping modules are mechanical clamping elements that are offered together with a universal clamping plate as a kit. Alternatively the clamping modules contain clamps or swing clamps with the corresponding support elements.
The universal clamping plate is provided with a grid for mounting of the clamping elements. This allows flexible positioning of the clamping elements for clamping of very different workpieces.

Clamping modules - hydraulic
Hydraulic clamps with universal clamping plate and screw pump
max. clamping force 2.5 kN

The modulog clamping module consists of 2 clamping elements, which are connected by hydraulic hoses to a screw pump. For each clamping element a corresponding fixed stop can be positioned on the universal clamping plate.
The universal clamping plate is provided with a grid for mounting of the clamping elements. This allows flexible positioning of the clamping elements for clamping of very different workpieces.
Also the screw pump is fixed on the universal clamping plate.

modulog module programme for handling technology
Complete new product range for the handling of workpieces up to 1,000 kg

The modulog module system consists of individual modules which realise a basic function for the handling of workpieces.
Modules for horizontal and vertical rotating, tilting as well as lifting of workpieces are available. This range is completed by cart and floor modules for displacement and installation of the units.
All modules are complete functional units that can be easily combined to built multi-functional units. So there are many possibilities to to use a system directly adapted to the corresponding demands.

All details on our new modulug modular programme are
in our new catalogue "Assembly and handling technology"
